What is Ohms
Ohms, symbolized by the capital letter "Ω," is the standard unit of electrical resistance. Named after German physicist Georg Simon Ohm, this unit is used to measure the resistance offered by a material or device to the flow of electric current. Resistance is a fundamental property in electrical circuits, influencing the current and voltage in a circuit.
History of Ohms
Georg Simon Ohm, born in 1789 in Erlangen, Bavaria, was a German physicist and mathematician. Ohm formulated Ohm's Law, which relates voltage, current, and resistance in a circuit. His groundbreaking work laid the foundation for understanding electrical circuits and resistance, leading to the establishment of the unit "Ohm" in his honour.
What is Megohm
Megohm, also known as "megaohm" or "million ohms," is a metric unit of electrical resistance equal to one million ohms (1,000,000 ohms). It is often used to represent very high levels of resistance in electrical components.
History of Megohm
The concept of a "megaohm" as a unit of electrical resistance emerged as the need arose to measure extremely high levels of resistance. The prefix "mega-" comes from the Greek word "megas," meaning "great" or "large." Megohms play a critical role in electrical engineering, especially in fields like telecommunications and high-voltage systems.
How Many Ohms Are in a Megohm?
As mentioned earlier, one megohm is equivalent to one million ohms. In mathematical terms, 1 Megohm = 1,000,000 Ohms.
How to Convert Ohms to Megohm
